Abstract
The length of the A.C.O. storage ring laser is 5.50 meters, on each side of the undulator is a vacuum system monted with bellows in which the laser cavity mirrors are placed. The mechanical feed thoughs for the mirror adjustments have an accuracy of 1 µmeter for the length 10-6 Rd. for the angles.
